YARN-WINDING MACHINE.

Specification of Letters Patent.

. Patented Mar. 5, 1912.

Application filed May 10, 1911. Serial No. 626,149.

To all whom it may concern:

Be it known that I, ALFRED K. MILLER, a citizen of the United States, residing at orcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Yarn- VVinding Machines, of which the following is a specification.

This invention relates to a machine to -control and regulate the winding of woolen, worsted, cotton, or other yarn, on a bobbin, section, beam or other container.

The object of the invention is to provide a machine which will make each strand of yarn in each layer that is wound upon any such bobbin or container occupy the same space thereon as every other strand and to make the diameter of the growing bobbin or other container uniform at every point at any given number of revolutions. A practi cal result of establishing such a uniform diameter is that when the strands of yarn are taken from the bobbin or other container on which they been wound by the operation of this machine, to a second bobbin or other container, each strand thus taken off is delivered at the same tension and at the same rate and is equal in yardage to every other strand. This machine produces such a uniformity of diameter in the growing bobbin, section, beam or other container, in the following manner. A gage device having a lateral surface equal in length to the winding surface of the'bobbin or other container is placed adjacent to such winding surface at such a point as to leave a fixed space between this gage surface and the bobbin or other container for the first layer of yarn to be wound thereon. As the yarn is wound on the bobbin or other container this gage surface moves backward through the operation of a mechanical device later described, the speed of such retreat being always proportional to the revolution of the bobbin or other container, so that the space between the moving gage surface and the winding surface of the bobbin or other container in which each succeeding layer of yarn must run is always the same.

'Referring'to the drawings, Figure 1, is a top plan, Fig. 2 is a side elevation, Fig. 3, an end elevation, and Fig. 4, a sectional view on-line indicated by 1-4.

Referring to F ig. 4:, (1 indicates the gage surface above referred to, said gage being shown as a drum or roller; b indicates the bobbin or other container. Referrlng now to Figs. 1 and 2 it will be seen that this gage, drum or roller is connected to the shaft on which the bobbin or other container is revolved by a series of gears and by beveled gears and by a threaded shaft. These gears are shown at c d and e f and the beveled gears are shown at g and h in Fig. 1, and the threaded shafts at 2' in Fig. 1. This gage surface, drum or roller is suspended from the threaded shaft being supported by two blocks shown at j in Fig. 1, the inside of the blocks through which the shaft passes being threaded to correspond with the threads on the shaft. driven by power connecting with a double pulley shown at 7c Z in Fig. 1. As the bobbin or other container revolves the gears, beveled gears and threaded shaft also re volve and the gage surface, drum or roller resting on such shaft through the operation of the threaded shafts 2' in blocks j, travels backward along the threads on the shafts, the rapidity of such retreat being always proportional to the revolutions of the bobbin or other container, thus leaving for each layer of yarn wound on such bobbin or other container a space between the gage surface, and winding surface equal to that occupied by each previous layer. The relation between the revolution of the bobbin or other containerandthe retreat of the gage surface can be varied by changing the gears shown at cl and f in Fig. 2, and the given space which is allowed for each layer of yarn can thus be varied in accordance with the size of the yarn to be wound on such bobbin or other container or the number of strands to be wound thereon. This change of gears is facilitated by lifting the lever m shown in Figs. 1 and 2, which throws the gears out of mesh, so that they can be easily removed. This lever, when the gears are in place,.is secured by a pin shown at y.

The machine as illustrated in the drawing is shown in connection with an examining frame, so that the yarn before passing on to the bobbin can be inspected and imperfections taken out. The strands of yarn on first reaching the machine at the point z The bobbin or other container is- Figs. 2 and 47, pass through a comb #1, and two rollers 2, 3, and then pass along the top of the machine where the inspection takes place, to roller 4:, then upward through a second comb 5, and over the roller 6 and downward through a reducing reed 7 to another roller 8, passing from there direct to the winding surface of the bobbin or other container, on which they are wound under the conditions produced by the adjacent gage surface, as before set forth. After the bobbin or other container has the desired amount of yarn wound thereon, it can be removed from the machine and another empty one substituted, the shaft on which the bobbin or other container revolves being constructed to allow this to be done. Couplings to enable the bobbin or other container to. be removed are indicated at w in Fig. 8.

No mechanism is shown in the accompanying drawings for returning the gage surface to its primary situation preparatory to. winding a second and successive bobbins or other containers, but this can be accomplished by reversing the running of the machine, the speed of such return being accelerated by a separate set of gears or other mechanical device.

By using the same gears cl and f shown in Fig. 2, and the same adjustment in winding two or more bobbins, or other containers, and by revolving the winding surfaces of all, the same number of revolutions, it is thus possible to. insure equal yardage and; equal conditions in the winding on the several bobbins thus wound. They can afterward be unwound together from a com.- mon shaft without variation in the length or tension in the strands of yarn on the several bobbins, sections, or other containers.

Having thus described my invention I de clare that what I claim as new, is,
